安裝RAC做oracle叢集件要求出現錯誤，錯誤資訊如下：

 1 [[email protected] grid]$ ./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -fixup -verbose 2  3 Performing pre-checks for cluster services setup  4  5 Checking node reachability... 6  7 Check: Node reachability from node "rac1" 8   Destination Node                      Reachable?               9   ------------------------------------  ------------------------10   rac2                                  yes                     11   rac1                                  yes                     12 Result: Node reachability check passed from node "rac1"13 14 15 Checking user equivalence...16 17 Check: User equivalence for user "grid"18   Node Name                             Comment                 19   ------------------------------------  ------------------------20   rac2                                  passed                  21   rac1                                  failed                  22 Result: PRVF-4007 : User equivalence check failed for user "grid"

一開始的思路是rac1 ssh rac2，rac2 ssh rac1；驗證通過後執行命令後還是報同樣的錯誤，代碼如下：

1 ./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -fixup -verbose

後來在論壇中發現一篇文章，裡面提到，叢集不僅要驗證對方，同時也要驗證自己：

 1 [[email protected] ~]# su - oracle 2 [[email protected] ~]$ ssh rac2 date 3 The authenticity of host ‘rac2 (127.0.0.1)‘ can‘t be established. 4 RSA key fingerprint is 00:38:d0:f8:99:20:fa:41:90:d6:9b:68:06:68:d8:15. 5 Are you sure you want to continue connecting (yes/no)? yes 6 Warning: Permanently added ‘rac2‘ (RSA) to the list of known hosts. 7 Fri Aug 17 12:49:01 CST 2018 8 [[email protected] ~]$ ssh rac2priv date 9 The authenticity of host ‘rac2priv (172.16.0.92)‘ can‘t be established.10 RSA key fingerprint is 00:38:d0:f8:99:20:fa:41:90:d6:9b:68:06:68:d8:15.11 Are you sure you want to continue connecting (yes/no)? yes12 Warning: Permanently added ‘rac2priv,172.16.0.92‘ (RSA) to the list of known hosts.13 Fri Aug 17 12:49:09 CST 201814 [[email protected] ~]$ su - grid15 Password: 16 [[email protected] ~]$ ssh rac2 date17 The authenticity of host ‘rac2 (127.0.0.1)‘ can‘t be established.18 RSA key fingerprint is 00:38:d0:f8:99:20:fa:41:90:d6:9b:68:06:68:d8:15.19 Are you sure you want to continue connecting (yes/no)? yes20 Warning: Permanently added ‘rac2‘ (RSA) to the list of known hosts.21 [email protected]‘s password: 22 Permission denied, please try again.23 [email protected]‘s password: 24 Fri Aug 17 12:49:33 CST 201825 [[email protected] ~]$ ssh rac2priv date26 The authenticity of host ‘rac2priv (172.16.0.92)‘ can‘t be established.27 RSA key fingerprint is 00:38:d0:f8:99:20:fa:41:90:d6:9b:68:06:68:d8:15.28 Are you sure you want to continue connecting (yes/no)? yes29 Warning: Permanently added ‘rac2priv,172.16.0.92‘ (RSA) to the list of known hosts.30 [email protected]‘s password: 31 Fri Aug 17 12:49:43 CST 2018

隨後再執行命令就全部pass（通過）。
